Vue封装的过渡与动画: 在插入、更新或移除DOM元素时,在合适的时候给元素添加样式类名。
写法:
<transition name="hello" appear>
<h1 v-show="isShow">你好啊!</h1>
</transition>
<style>
.hello-enter-active{
animation: hello 0.5s linear;
}
.hello-leave-active{
animation: hello 0.5s linear reverse;
}
@keyframes hello {
from{
transform: translateX(-100%);
}
to{
transform: translateX(0px);
}
}
</style
4.备注: 若有多个元素需要过渡,则需要使用 ,且每个元素都要指定 key值
<transition-group name="hello" appear>
<h1 v-show="!isShow" key="1">你好啊!</h1>
<h1 v-show="isShow" key="2">尚硅谷!</h1>
</transition-group>
5.第三方动画库 Animate.css 网站:https://www.npmjs.com/package/animate.css
安装完成后,直接引用样式 import ‘animate.css’
<transition-group appear
name="animate__animated animate__bounce"
enter-active-class="animate__swing"
leave-active-class="animate__backOutUp">
<h1 v-show="!isShow" key="1">你好啊!</h1>
<h1 v-show="isShow" key="2">尚硅谷!</h1>
</transition-group>
